Email: Mobile: 860-***-**** Qualification Summary

Data-driven research background and trained for both analytical and intuitive thinking. I approach problems through visualization and connection of patterns found within interdisciplinary scientific theory. By developing this approach, I systematically implement facile mechanistic motifs for advanced material outputs. My research background bridges material science and biology to gain multiscale understanding of natural systems aimed towards bioinspired structure-function properties. Through top-down and bottom-up consideration of design inputs, I have developed a strong background in polymer science, biopolymer processing, and nano to macroscale characterization. Material Development: Biopolymer processing, structure-function relationships, fibrous materials, polymer self- assembly, polymer-solvent dynamics, bioinspired material design, peptide material functionalization for bioactive response, silk fibroin platforms: gel, fiber, film, and hard materials. Characterization: FTIR, DMA, instron testing, TGA, polarized microscopy/birefringence, SEM Biomedical Engineering: In vitro and in vivo data processing and analyses, drug delivery material design, cell culture

Mechanical Design: Medical Device Fabrication, Prototyping, product development, scale-up PROFESSIONAL
